Polyglyceryl-4 Isostearate CAS No.: 91824-88-3
Polyglyceryl-4 Isostearate is an ingredient commonly used in cosmetics as an emulsifier and stabilizer. It is derived from the esterification of isostearic acid with polyglycerin. This compound helps to blend and stabilize the oil and water phases in cosmetic formulations, ensuring a consistent and homogeneous product.This ingredient is valued for its ability to improve the texture and spreadability of cosmetic products, allowing for smoother application and enhancing the overall stability of formulations. The chemical formula of Polyglyceryl-4 Isostearate is C30H68O14.
Origin
Polyglyceryl-4 Isostearate is produced through a chemical process known as esterification. Isostearic acid, derived from the hydrogenation of plant oils, is reacted with polyglycerin, resulting in the formation of the ester. This esterification process involves combining the acid and alcohol groups, leading to the creation of Polyglyceryl-4 Isostearate. The resulting compound is then purified and used as an ingredient in cosmetics for its emulsifying and stabilizing properties.
